Stop and observe any web page to check if there is anything suspicious like false advertisements and file download requests. Avoid visiting any sites that contain adult content, torrent downloading, peer to peer file sharing and sites containing pop ups that make suspicious offers. Avoid downloading software from the internet unless you are absolutely sure that the software is safe and legal. It is recommended to use an antivirus such as AVAST. Antiviruses are programs that can detect unsafe software and files, they can isolate and remove known threats and can perform background scans on your computer to catch any hidden threats in your computer. AVAST offers a boot time scan that you can schedule for the next time you boot your computer and will scan it before booting your current operating system. An antivirus can also warn you when you visit unsafe webpages and unsafe file downloads and can provide security for your personal information whenever you log into a site.
